The country of Japan trembled once more as a magnitude 7.1 earthquake struck off the coast of the ravaged Miyagi Prefecture on Thursday night.

Hundreds of locals evacuated their homes along the northern coast after tsunami advisories were issued.

An hour later, the warnings were lifted as no tsunami waves were created by the temblor, which was the strongest of the aftershocks that have followed the magnitude 9.0 quake in March.

In a press conference today, the Tokyo Electric Power Company assured the public that no further damage was done to the crippled Fukushima nuclear power plant.

However, Onagawa nuclear power plant located near the epicenter of the quake was damaged, causing the plant to lose power. The plant’s reactors, however, had not been dependent on the two power lines damaged in the earthquake.

Japan’s Meteorological Agency reported that no increased radiation levels were detected around the Onagawa plant and cooling systems remained online.
